Question

is this a sentence fragment? using instruments called geophones, scientists measuring seismic waves caused by traffic to learn how urban life affects the earth. yes no

Explanation:

A sentence fragment is an incomplete sentence that lacks a main verb or a complete thought. In the given sentence, "scientists measuring seismic waves..." has a participle "measuring" instead of a main verb. The correct structure should have a main verb like "are measuring" to make a complete sentence. So this is a sentence fragment.

Answer:

yes
